Ruby 1.9.3p327 で rvm を使用して Rails 3.0.20 アプリを実行しています。私のGemfileの読み取り:
gem 'image_science', :git => 'git://github.com/asynchrony/image_science.git'
Gemfile.lock のバージョンは次のとおりです。
remote: git://github.com/asynchrony/image_science.git
revision: dc36ddaadc46aecdef907de3c41a9d14d28ba8d8
specs:
image_science (1.3.2.1.Asynchrony)
次のエラーが発生し続けるため、image_science を削除しないとアプリを起動できないようです。
